How can I add fixed-width space to beginning of HStack? - swift

In SwiftUI I am adding buttons to an HStack. I want a space of a fixed width at the beginning of the HStack. Currently the buttons are directly up against the left edge of the screen and I want a space of 64px before the first button. I cannot seem to find an answer to this, my Google-Fu may be failing me.
Here is what I have:
struct MyView: View {
var body: some View {
HStack(alignment: .center, spacing: 12, content: {
Button(action: doThis) {
Image("this").resizable().aspectRatio(contentMode: .fit)
}.frame(width: 38, height: 38, alignment: .center)
Button(action: doThat) {
Image("that").resizable().aspectRatio(contentMode: .fit)
}.frame(width: 38, height: 38, alignment: .center)
Spacer()
})
}
func doThis() {}
func doThat() {}
}

Just add some padding on the left.
struct ContentView: View {
var body: some View {
HStack(alignment: .center, spacing: 12, content: {
Button(action: doThis) {
Image("this").resizable().aspectRatio(contentMode: .fit)
}.frame(width: 38, height: 38, alignment: .center)
.padding(.leading, 64) /// here!
Button(action: doThat) {
Image("that").resizable().aspectRatio(contentMode: .fit)
}.frame(width: 38, height: 38, alignment: .center)
Spacer()
})
}
func doThis() {}
func doThat() {}
}

Content is shown behind the navigation bar when the text field is active

when I use the textfield in my View, the Content in the vstack or scrollview is seen behind the custom navigation bar. How can I fix this background problem?

Fit Image & Text in Frame SwiftUI

I have two problems with my code.
I want to fit my Image into the frame I created. The image format is not the same with that of the frame, I would rather have just part of the image there instead of white borders.
The title text I created with the blur background should fit into the bottom of the frame.
struct VisualEffectView: UIViewRepresentable {
var effect: UIVisualEffect?
func makeUIView(context: UIViewRepresentableContext<Self>) -> UIVisualEffectView { UIVisualEffectView() }
func updateUIView(_ uiView: UIVisualEffectView, context: UIViewRepresentableContext<Self>) { uiView.effect = effect }
}
struct ContentView: View {
var body: some View {
ZStack {
Color.black.edgesIgnoringSafeArea(.all)
ZStack {
Image("Yosemite")
.resizable()
.scaledToFill()
.overlay(content: {
Text("Lorem ipsum dolor sit amet")
.font(.largeTitle)
.fontWeight(.bold)
.multilineTextAlignment(.leading)
.fixedSize(horizontal: false, vertical: true)
.foregroundColor(.white)
.background(VisualEffectView(effect: UIBlurEffect(style: .systemMaterialDark)))
.frame(minWidth: 350, maxWidth: .infinity, minHeight: 250, maxHeight: .infinity, alignment: .bottom)
.scaledToFit()
})
}.padding()
.frame(width: 350, height: 400)
.background()
.clipShape(RoundedRectangle(cornerRadius: 30))
}
}
}
I don't know about your blur background, but the rest would work like this:
struct ContentView: View {
var body: some View {
ZStack {
Color.black.edgesIgnoringSafeArea(.all)
Image("image")
.resizable()
.scaledToFill()
.frame(width: 350, height: 400)
.cornerRadius(30)
.overlay {
Text("Lorem ipsum dolor sit amet")
.font(.largeTitle)
.fontWeight(.bold)
.multilineTextAlignment(.leading)
.foregroundColor(.white)
.padding(.horizontal, 8)
.background(.ultraThinMaterial)
.frame(maxHeight: .infinity, alignment: .bottom)
.padding()
}
}
}
}

How to Clear a Textfield with a Button (Swift UI)

I am trying out to implement a Mailview like I've seen in a tutorial before.
After solving the layout, I tried to get some features on it.
If I begin to write a new message, I want to clear the filled Textfield boxes, when the user clicks the trash bin. But however I don't find out how to clear it.
import SwiftUI
var inboundMails = [[String()]]
var outboundMails = [[String()]]
struct ContentView: View {
#State var showComposeMessageView: Bool = false
var body: some View {
TabView
{
NavigationView
{
List (0 ..< 6)
{
_ in
NavigationLink(destination: Text("Nachrichtentext"))
{
SingleMessageView()
}
}
.listStyle(GroupedListStyle())
.navigationTitle("Inbox")
.navigationBarItems(trailing:
Button(action: { showComposeMessageView.toggle() }, label: {
Image(systemName: "square.and.pencil")
})
)
}
// Verfassen Button
.sheet(isPresented: $showComposeMessageView, content:
{
NewMessage()
}) //.sheet
.tabItem {
Image(systemName: "envelope.fill")
Text("Inbox")
}
Text("Sent")
.tabItem {
Text("Sent")
Image(systemName: "paperplane.fill")
}
}
}
}
// Design eines einzelnen Nachrichtenblocks

How can I add a button in SwiftUI

How can I add a button at this location in SwiftUI? I have a textfield and a background being used, but I'm not sure how you can add a button to this location, like a bar button in swift.
My code:
struct MyTextField: View
{
#ObservedObject var model: TextFieldModel
var body: some View
{
VStack(spacing: 0)
{
Color.black
.frame(height: 100)
.overlay(Image(("appIconLogo")).resizable().frame(width: 70, height: 70),
alignment: .bottom)
.edgesIgnoringSafeArea(.top)
VStack(alignment: .leading, spacing: 10)
{
Text("Welcome!")
.font(.system(size: 60, design: .rounded))
.foregroundColor(.black)
.padding(.leading)
iTextField("Search Your Ticker", text: $model.text, isEditing: $model.isEditing)
.foregroundColor(.black)
.showsClearButton(true)
.autocapitalization(.allCharacters)
.disableAutocorrection(true)
.returnKeyType(.search)
.onReturn
{
print($model.text)
NotificationCenter.default.post(name: Notification.Name(rawValue: "isValidTicker"), object: nil)
}
.foregroundColor(.black)
.style(height: 58, font: nil, paddingLeading: 25, cornerRadius: 6, hasShadow: true, image: Image(systemName: "magnifyingglass"))
.foregroundColor(.black)
}.frame(maxWidth: .infinity, alignment: .leading)
}.frame(maxHeight: .infinity, alignment: .top)
}
}
I assume you wanted something like this
Color.black
.frame(height: 100)
.overlay(Image(("appIconLogo")).resizable().frame(width: 70, height: 70), alignment: .bottom)
.overlay(Button("Perform") {}.padding(), alignment: .leading) // << here!!
.edgesIgnoringSafeArea(.top)
Any particular reason you have the Color.black with an overlay for the logo? Using your code, wrapping it in a ZStack should work
ZStack(alignment: .leading) {
Color.black
.frame(height: 100)
.overlay(Image(("appIconLogo")).resizable().frame(width: 70, height: 70), alignment: .bottom)
.edgesIgnoringSafeArea(.top)
Button(action:{}) {
Text("Button Text")
}
}

How can I make the list wider in SwiftUI?

I'm learning SwiftUI right now and I'm working on a tutorial.
But in SwiftUI List, the part of name is cut like the picture. Do you have a modifier?
struct ContentView: View {
var body: some View {
List(modelData) {
Device in HStack {
Image(systemName: Device.image)
.frame(width: 50, height: 10, alignment: .leading)
Text("\(Device.name)")
.frame(width: 50, height: 10, alignment: .leading)
.scaledToFit()
VStack {
Text("\(Device.price)")
}
}
.font(.title)
}
}
}
Instead of limiting as you do
Text("\(Device.name)")
.frame(width: 50, height: 10, alignment: .leading)
.scaledToFit()
use just
Text("\(Device.name)")
It will be automatically sized to fit
